Main Question or Discussion Point
2as = v^2 but why do they have the formula 2as = v^2-vo^2 displayed as correct with out a reference that its wrong. In Basic physics classes it may not even be mentioned that its wrong. I understand that no one is teaching relativistic physics but why not even mention it. Its been over a 100 years and its still being used in physics books today as being correct along with other formulae dealing with the past.
